This interactive program focuses on the role of sea level in climate change. Sections include an overview and a list of relevant NASA satellite missions and their objectives. A third section, entitled Global View, covers the following 5 topics:...(View More) Latest View, Large El Niño, Hurricane Katrina, Indian Ocean Tsunami, and La Niña.(View Less)

This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and...(View More) greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.(View Less)

In this paper and pencil exercise, students create graphs that describe the effect of a series of experiments using Daisy World, an energy balance model, that can be used to demonstrate concepts of equilibrium, homeostatis, and positive and negative...(View More) feedbacks. Internet access and exploration with the actual Daisy World model is ideal, but not required. The resource is Activity 6 of the learning module, Global Balance, part of the lesson series Potential Impacts of Climate Variability and Change.(View Less)

This is a lesson about the effects of large impacts. Learners will use critical thinking skills to evaluate and apply data from a narrative to a scientific selection process, will demonstrate or visualize simulations of some of the effects of a huge...(View More) impact, and will write a point of view narrative. Materials and vocabulary lists, and advanced preparation and procedural tips are included. This is lesson 14 of 19 in Exploring Meteorite Mysteries.(View Less)
